Unable to include some vtk classes in c++ plugin

I am currently unable to include the vtkSTLReader class and vtkNamedColors class in a c++ plugin. I believe my issues are with the cmake files. I included the plugin here: pvOptUMesh.zip (31.2 KB) It is being built from the pvOptUMesh directory against paraview superbuild v5.9.1

You are missing target_link_libraries in your CMakeLists.txt, see here:
